使用ifstream和getline读取文件内容[c++] ZZ

假设有一个叫 data.txt 的文件, 它包含以下内容:

Fry: One Jillion dollars.
[Everyone gasps.]
Auctioneer: Sir, that's not a number.
数据读取， 测试 。

以下就是基于 data.txt 的数据读取操作:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

//输出空行
void OutPutAnEmptyLine()

//读取方式: 逐词读取, 词之间用空格区分
//read data from the file, Word By Word
//when used in this manner, we'll get space-delimited bits of text from the file
//but all of the whitespace that separated words (including newlines) was lost.
void ReadDataFromFileWBW()

//读取方式: 逐行读取, 将行读入字符数组, 行之间用回车换行区分
//If we were interested in preserving whitespace,
//we could read the file in Line-By-Line using the I/O getline() function.
void ReadDataFromFileLBLIntoCharArray()

//读取方式: 逐行读取, 将行读入字符串, 行之间用回车换行区分
//If you want to avoid reading into character arrays,
//you can use the C++ string getline() function to read lines into strings
void ReadDataFromFileLBLIntoString()

//带错误检测的读取方式
//Simply evaluating an I/O object in a boolean context will return false
//if any errors have occurred
void ReadDataWithErrChecking()

int main()
{
ReadDataFromFileWBW(); //逐词读入字符串
OutPutAnEmptyLine(); //输出空行

ReadDataFromFileLBLIntoCharArray(); //逐词读入字符数组
OutPutAnEmptyLine(); //输出空行

ReadDataFromFileLBLIntoString(); //逐词读入字符串
OutPutAnEmptyLine(); //输出空行

ReadDataWithErrChecking(); //带检测的读取
return 0;
}

输出结果为:
Read from file: Fry:
Read from file: One
Read from file: Jillion
Read from file: dollars.
Read from file: [Everyone
Read from file: gasps.]
Read from file: Auctioneer:
Read from file: Sir,
Read from file: that's
Read from file: not
Read from file: a
Read from file: number.
Read from file: 数据读取，
Read from file: 测试
Read from file: 。

Read from file: Fry: One Jillion dollars.
